Description
Technical Field
[0001] The embodiments of this disclosure relate to the field of winding machine drum replacement tooling technology, specifically, to a winding machine drum replacement tooling. Background Technology
[0002] A coiler is an auxiliary device in a steel rolling mill that coils hot-rolled or cold-rolled steel into a coil shape. On hot strip mills, cold strip mills, and wire rod mills, it is positioned after the finishing mill stand. On single-stand reversible cold strip mills, it is installed before or after the mill. In addition, it is also installed in various finishing units such as continuous pickling lines, slitting lines, annealing lines, and coating lines. Coilers are used in many industries, with steel plate coilers in the metallurgical industry being the most representative. The drive source is either electricity or fluid.
[0003] In recent years, with the continuous development of the cold rolling industry, ensuring the high-quality development of cold-rolled products requires guaranteeing product quality and output. Equipment maintenance and stable operation are paramount. In the domestic cold rolling industry, Carosell coilers are generally used in pickling and continuous rolling mills. The coiling area equipment is a key piece of equipment, essentially the head of the cold rolling line. Due to the complex environment of the coiling area and the involvement of high-altitude operations, equipment maintenance and repair are difficult and time-consuming. In particular, equipment failures in the coiling area pose a high risk factor and are inconvenient to repair. Changing the coiler drum takes a long time, making rapid replacement difficult and increasing the time required for equipment maintenance and repair. Utility Model Content

[0031] like Figures 1-4 As shown, this embodiment illustrates a winding machine drum replacement fixture, including a fixed base 1, multiple fixing screws 2 on both sides of the fixed base 1, a V-shaped bracket 3, a clamping frame 4, a clamping plate 5, a clamping mechanism, a connecting frame 6, and a buffer pressing assembly. Compared to the technical problem of excessively long maintenance and repair times in the winding area of existing technologies, this embodiment, through the V-shaped bracket 3, achieves rapid lifting of the drum to be replaced, facilitating the installation or removal of the drum by workers, thereby reducing the maintenance and repair time in the winding area and improving efficiency. The working efficiency is improved by the cooperation of the card frame 4 and the card plate 5, which realizes the locking and limiting of the drum after it is lifted by the V-shaped bracket 3, thereby ensuring the stability of the drum on the V-shaped bracket 3. The locking mechanism realizes the locking and positioning of the card plate 5 after it is inserted into the card frame 4, thereby ensuring the stability of the card plate 5 after insertion, and thus ensuring the limiting effect of the card plate 5 on the drum. The buffer pressing component can press the drum after the card plate 5 is inserted into the card frame 4, further ensuring the stability of the drum on the V-shaped bracket 3 and improving the overall safety of the device.
[0032] like Figure 1 As shown, the V-shaped bracket 3 is installed on the upper side of the fixed base 1. Multiple retaining frames 4 are installed inside the V-shaped bracket 3, arranged symmetrically. A retaining plate 5 is inserted into the retaining frame 4. The cooperation of the V-shaped bracket 3, retaining frames 4, and retaining plate 5 enables rapid lifting and limiting of the drum, thus facilitating quick drum replacement and reducing maintenance time. Figure 2 As shown, the snap-fit mechanism is installed on the outside of the card frame 4, the connecting bracket 6 is installed on the upper side of the card plate 5, and the buffer-type pressing component is installed on the inner end of the connecting bracket 6, as shown. Figure 3As shown, the locking mechanism includes a housing 101, an adjusting rod 102, a transmission plate 103, a locking block 104, and a return spring 105. Limiting slide rails 7 are installed on both sides of the inner wall of the housing 101. The two limiting slide rails 7 are symmetrically arranged and are I-shaped. The transmission plate 103 is slidably connected to the limiting slide rails 7. The limiting slide rails 7 can limit the sliding of the transmission plate 103, thus ensuring the stability of the transmission plate 103 during sliding. Locking slots are provided on both sides of the locking plate 5. The width of the locking slots matches the width of the locking block 104. The locking block 104 can lock with the locking plate 5 through the locking slots, thus ensuring the stability of the locking plate 5 after it is inserted into the locking frame 4. The locking mechanism can achieve locking of the locking plate 5 after insertion, thus achieving limiting of the locking plate 5 after insertion, thereby ensuring the limiting effect of the locking plate 5 on the drum. Figure 4 As shown, the buffer-type pressing assembly includes a buffer component and a pressing component. The buffer component includes a cylinder 201, a guide post 202, a lifting plate 203, and a buffer spring 204. The pressing component includes a connecting post 301 and an arc-shaped pressing plate 302. An anti-slip pad is provided on the lower side of the arc-shaped pressing plate 302. The anti-slip pad increases the friction between the arc-shaped pressing plate 302 and the drum, thereby enhancing the pressing and limiting effect of the arc-shaped pressing plate 302 on the drum. The buffer-type pressing assembly can achieve buffered pressing of the drum after it is lifted by the V-shaped bracket 3, thereby further ensuring the stability of the drum on the V-shaped bracket 3 and improving the safety during drum replacement. Figure 1 As shown, safety railings 8 are installed on both sides of the fixed base 1. The safety railings 8 can protect the personnel who climb the device to operate it, thereby improving the overall safety of the device.
[0033] Working principle:
[0034] When using this tooling, first hoist the tooling to the top of the upper winding trolley, insert the fixed base 1 into the lifting body of the upper winding trolley, and then use the fixing screw 2 to fix the fixed base 1 and the lifting body. After fixing, drive the trolley to the bottom of the drum to be replaced, and the operator operates the lifting body of the upper winding trolley to rise. The lifting body drives the tooling to rise. During the rising process, the V-shaped bracket 3 inside the tooling lifts the drum. After lifting, the operator enters the safety guardrail 8 of the tooling from the side, and then inserts the clamping plate 5 into the clamping frame 4 so that the clamping plate 5 has a limiting effect on the drum. After all the fixing bolts used to install the drum equipment are removed, the upper winding trolley is used to drag out or reinstall the drum, thus completing the replacement of the drum.
